Recent Approaches in Quantum Dots Application for Biological System

open access: yesChemical Engineering Transactions, 2023
Quantum dots are semiconductor nanoparticles with optical and electronic (optoelectronic) properties that vary with size and composition. They distinguish themselves from traditional fluorescence dyes due to their high visibility, long-lasting, size ...

Quantum-dot thermometry [PDF]

open access: yesApplied Physics Letters, 2007
We present a method for the measurement of a temperature differential across a single quantum dot that has transmission resonances that are separated in energy by much more than the thermal energy. We determine numerically that the method is accurate to within a few percent across a wide range of parameters. The proposed method measures the temperature

Using spin bias to manipulate and measure quantum spin in quantum dots [PDF]

open access: yesPHYSICAL REVIEW B 77, 235309 (2008), 2008
A double-quantum-dot coupled to electrodes with spin-dependent splitting of chemical potentials (spin bias) is investigated theoretically by means of the Green's functions formalism. By applying a large spin bias, the quantum spin in a quantum dot (the dot 1) can be manipulated in a fully electrical manner.

Co-tunneling spin blockade observed in a three-terminal triple quantum dot [PDF]

open access: yesPhys. Rev. B 96, 155414 (2017), 2017
We prepare a triple quantum dot with a separate contact lead to each dot to study Pauli spin blockade in the tunnel-coupled three dots in a row. We measure the tunneling current flowing between the center dot and either the left or right dot with the left and right leads as a common source and the center lead as a drain. In the biased stability diagram,

A two-dimensional array of single-hole quantum dots [PDF]

open access: yes, 2020
Quantum dots fabricated using techniques and materials that are compatible with semiconductor manufacturing are promising for quantum information processing. While great progress has been made toward high-fidelity control of quantum dots positioned in a linear arrangement, scalability along two dimensions is a key step toward practical quantum ...

Photovoltaic Performance of a Nanowire/Quantum Dot Hybrid Nanostructure Array Solar Cell

open access: yesNanoscale Research Letters, 2018
An innovative solar cell based on a nanowire/quantum dot hybrid nanostructure array is designed and analyzed. By growing multilayer InAs quantum dots on the sidewalls of GaAs nanowires, not only the absorption spectrum of GaAs nanowires is extended by ...

Efficient Quantum Dot−Quantum Dot and Quantum Dot−Dye Energy Transfer in Biotemplated Assemblies [PDF]

open access: yesACS Nano, 2011
CdSe semiconductor nanocrystal quantum dots are assembled into nanowire-like arrays employing microtubule fibers as nanoscale molecular "scaffolds." Spectrally and time-resolved energy-transfer analysis is used to assess the assembly of the nanoparticles into the hybrid inorganic biomolecular structure. Specifically, we demonstrate that a comprehensive
